Abstract
The utility model discloses a kind of operation motor of crane and speed reducer protective covers, it includes cover body, ventilation hole is provided on the baffle on the outside of cover body, front band is fixed with by supporting rib in the middle part of cover body, the side of front band and lower catch hoop is hinged by articulated shaft, is equipped with U-shaped card in the inside of lower catch hoop, connecting plate is equipped in the opposite side of front band and lower catch hoop, corresponding position is provided with through-hole on upper and lower connecting plate, and bolt is equipped in through-hole and is equipped with wing nut with what bolt matched.The beneficial effects of the utility model are simple, fast can to protect the operation motor and speed reducer of crane using protective cover.
Description
Technical field
The utility model is related to the auxiliary device on crane, particularly a kind of operation motors suitable for crane
And the protective cover used on speed reducer.
Background technology
Electric block gantry crane cart service meter speed reducer is compact structure form, crane crossbeam
It is machined surface with the end face that speed reducer is combined, does not allow to weld the protection of supports support motor deceleration machine above
Cover, can not solve, the electric block gantry crane for producing and using now, cart in face of this problem manufacturer
For service meter speed reducer nearly all without protective cover, this results in motor deceleration captain's phase wind and weather of crane, contracting
The service life of motor deceleration machine is subtracted.
Invention content
The purpose of this utility model is a kind of operation motor rational in infrastructure, the preferable crane of using effect of design
And speed reducer protective cover.
The technical solution of the utility model is a kind of operation motor of crane and speed reducer protective cover, it is wrapped
Include cover body, it is characterised in that：Ventilation hole is provided on the baffle on the outside of cover body, is fixed with and blocked by supporting rib in the middle part of cover body
The side of hoop, front band and lower catch hoop is hinged by articulated shaft, U-shaped card is equipped in the inside of lower catch hoop, in front band and lower card
The opposite side of hoop is equipped with connecting plate, and corresponding position is provided with through-hole on upper and lower connecting plate, and bolt and bolt phase are equipped in through-hole
That matches is equipped with wing nut.
The beneficial effects of the utility model are being capable of simple, fast operation motor and speed reducer profit by crane
It is protected with protective cover, effectively extends the operation motor of crane and the service life of speed reducer.
Description of the drawings
Fig. 1 is the structure diagram of the utility model,
Fig. 2 is the usage state diagram of the utility model.
Specific embodiment：
Embodiment is described in detail with reference to the figures above,
A kind of operation motor of crane and speed reducer protective cover, it includes cover body 1, the baffle on the outside of cover body
On be provided with ventilation hole 2, be hollow design on the inside of cover body, front band 10, front band be fixed with by supporting rib 12 in the middle part of cover body
It is hinged by articulated shaft 9 with the side of lower catch hoop 8, U-shaped card 7 is equipped in the inside of lower catch hoop, in the another of front band and lower catch hoop
Side is equipped with connecting plate, and corresponding position is provided with through-hole on upper junction plate 3, lower connecting plate 5, and bolt 4 and spiral shell are equipped in through-hole
What bolt matched is equipped with wing nut 6.
The utility model left and right on lower catch hoop inside circumference position it is each welding one U-shaped card, install protective cover when this two
A U-shaped card is promoted inwardly along the cooling fin of motor casing by motor outside, when protective cover inner end is apart from crane
Stop during 3~5 ㎜ of crossbeam end face, stay this apart from the reason of be protective cover vibration and crane when preventing the crane from running
Crossbeam end face generates friction, the two U-shaped cards are stuck on the cooling fin of 11 shell of motor, and the cooling fin of motor casing, which rises, to be slided
Road acts on, and tightening butterfly spiral shell at this time makes upper and lower clip be fastened on the circumference of motor, and then has fixed entire cover body, cover
Punching has ventilation hole on the baffle of external side, ensures fully to radiate during motor running.
The above embodiments are merely examples for clarifying the description, and is not intended to limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and the obvious variation or change thus extended out
Within the dynamic protection domain created still in the utility model.
